The original +5VDC supplies for c/t pinballs were usually 3 to 5 amps.
Modern switching ATX computer power supplies are normally 15 - 25 amps.
So...no problem! The only issue using an ATX supply is you have to
bypass (short to common) the control line so the supply will turn ON
when plugged in.
And also make sure the supply can ventilate itself, it won't run hot,
but if the input or exhaust lovres are covered then it will fail
sooner. There is enough air flow within the cabinet so you don't need
to add an extra opening for the power supply.
